Uyilungisa kanjani i-air conditioning ku-BMW

Abanikazi bama-BMW, ​​ikakhulukazi amamodeli e-E39 kanye ne-E53, bayakwazi ukuzwa izikhalo zokuthi injini iqala ukushisa ngokweqile uma isifudumezisi sisebenza, ikakhulukazi emazingeni okushisa aphezulu kanye nokubhajwa esiminyaminyeni. Izizathu zokuwohloka, okuholela ekulungisweni okwengeziwe kwe-air conditioner ku-BMW, ​​zingahluka.

Izimbangela zokuwohloka kwe-air conditioner yakwaBMW

Ukungasebenzi kahle okuvame kakhulu ukwehluleka kwesiphephetha-moya. Lokhu ukungasebenzi kahle kakhulu uma kungenzeka ukuthi i-air conditioner ingakwazi ukusebenza ngendlela evamile. Yiqiniso, kukhona ithuba lokushayela ngedivayisi engasebenzi, kodwa akekho ozoqinisekisa ukuthi ngeke kudingeke ulungise isimo somoya, noma ngisho nesistimu yonke yenjini.

Ukuzilungisa ngokwakho ukuwohloka okunjalo akuyona inketho enhle kakhulu, ikakhulukazi ezimotweni ezivuselelwe kabusha. Kodwa phakathi kwabathandi bezimoto zaseJalimane kukhona abadwebi abanokuhlangenwe nakho ekulungiseni idivayisi enjalo ezimweni zegaraji.

Okokuqala, lapho usebenza eRussia, ama-air conditioner emoto ahluleka ngenxa yoshintsho olusheshayo lokushisa. Idivayisi imane imelane nemithwalo eyengeziwe emazingeni okushisa angaphansi kwe-zero kuze kufike ku--40 degrees, kanye nezinga lokushisa elifanayo elinophawu lokuhlanganisa ehlobo.

Ezimweni eziningi, kuthatha iminyaka engu-3-4 ukuthi amamodeli aphelelwe yisikhathi aguge ngokuphelele i-fan motor. Uma ukungasebenzi okunjalo kwenzeka emotweni entsha, lokhu kungumshado.

Hlobo luni lomonakalo ongenzeka?

Ngaphambi kokuqhubeka nokulungisa, udinga ukunquma ukuthi yini ukungasebenzi kahle okungenzeka. Kungenzeka:

•       isigaba sokuphuma kwabalandeli;
•       i-fan relay;
•       i-fan motor;
•       umthombo wamandla;
•       lawula ukuphuma kwe-voltage.

Ukuhlolwa kwamandla

Okokuqala, udinga ukuhlola ukusebenza kwenjini ngokwayo. Ukuze wenze lokhu, inikezwa nge-voltage engu-12V, enezintambo eziluhlaza okwesibhakabhaka nezinsundu ezixhuma ibhodi kanye ne-motor. Intambo yesithathu iyadingeka ukuze kulawulwe ukususa kwe-relay.

Uma konke kusebenza, umshayeli unenhlanhla - udinga nje ukuthola nokushintsha ezinye izingxenye. Uma injini ingajiki, kuzodingeka uthenge entsha, okudinga imali eningi.

Uma unezesekeli zemoto ezidingekayo, ukulungiswa kuzothatha cishe amahora ama-2. Ochwepheshe abanolwazi bakweluleka ukuthi uqale uthintane nochwepheshe bezogesi wezimoto, ngenxa yokuwohloka kwekhwalithi yezingxenye ezikhiqizwa ngaphansi kwelayisensi yakwa-BMW.

Ukulungisa i-BMW Compressor

I-air conditioning system ezimotweni zakwaBMW ibhekele izinga lokunethezeka komshayeli nabagibeli. Kuphela ngenxa yobukhona babo, bangazizwa bekahle emotweni lapho kushisa. Enye yemishini eyinhloko yalolu hlelo yi-compressor, umsebenzi wayo ukuqinisekisa ukujikeleza kwefriji ohlelweni. Singasho ngokuphepha ukuthi ngaphandle kokuba khona kwe-compressor, ukusebenza kwesistimu kuyomane kungenzeki.

Ukusebenza kwalolu hlelo kulula kakhulu. Ngosizo lwe-BMW compressor, i-freon ijova kurediyetha, lapho igesi ipholiswa khona futhi iguqulwe ibe uketshezi ngesenzo se-fan. Uma igesi ingekho eyanele noma kukhona okweqile, lokhu kudala imithwalo eyengeziwe kwi-compressor ye-BMW, ​​ngokuguga okushesha kwezakhi zayo.

Ngenxa yalokhu, ukugcinwa okuvamile kubaluleke kakhulu, lapho kufanele kuqashelwe futhi ku-air conditioning yezimoto ze-BMW.

Izimpawu eziyinhloko zokungasebenzi kahle kwe-compressor

Izinkinga ezivame kakhulu zesistimu ye-air conditioning yilezi:

•       Inani elinganele lomoya obandayo ku-cabin kanye nokubukeka kwe-liquid streaks, okuyisibonakaliso sokucindezeleka kwesistimu;
•       Ukubonakala kwemisindo engaphandle, ekhombisa ukuguga kwamavalvu namapiston e-compressor.

Uma sikhuluma ngokulungiswa kwe-compressor ye-BMW, ​​okokuqala, lokhu kuwukuhlaziywa kwezakhi zayo zokusebenza ngokombono wezobuchwepheshe. Okokuqala, ileveli ye-freon ihlolwa ngokuxilonga idivayisi.

Esikhathini esizayo, i-compressor iyahlakazwa futhi ihlakazwe, ikhwalithi nokusebenza kwezakhi zayo ngayinye kuyahlolwa. Ukulungiswa okuvame kakhulu kwe-compressor yemoto ye-BMW kuyisidingo sokushintsha i-bearing, i-solenoid valve, ipuleti lokucindezela noma iqembu le-piston.

Ngakolunye uhlangothi, kufanele kuqashelwe ukuthi ukulungisa i-compressor ye-BMW kuzobiza kancane kunokuthenga entsha. Inqubo yokulungisa i-compressor ngokwayo iyinkimbinkimbi kakhulu: idinga ulwazi oluthile, amathuluzi akhethekile kanye nemishini.

Akufanele sikhohlwe mayelana nokulimaza kokwakheka kwamakhemikhali egesi ye-freon, okuzofanele nakanjani ubhekane nayo ngesikhathi sokulungisa. Le gesi ingaba yingozi esikhumbeni futhi ibangele ukusha. Kungakho-ke akukhuthazwa kakhulu ukwenza umsebenzi wokulungisa ku-compressor ye-BMW.

Idizayini yokuguqulwa kwenjini ngayinye ihlinzeka ngezinketho ezimbili ze-tensioner: mechanical noma hydraulic.

I-compressor ishayelwa ibhande elizibambayo elinezimbambo ze-V.

Ngaphambi kokukhipha ibhande, kufanele ulungise isiqondiso sokuzungeza ngomcibisholo odwetshwe ngomaka uma uhlela ukuphinda uyisebenzise. Ukuma kwebhande kufanele kwenziwe kuphela ngokuhambisana nokumaka okunamathiselwe.

Uma ibhande lingcoliswe i-coolant, hydraulic fluid noma amafutha, kufanele lishintshwe. Ngokudluliswa kwe-V-belt, lokhu kwenziwa ngaphansi kwezimo ezilandelayo:

•       Ukungcoliswa ngefriji noma amafutha;
•       Ukubonakala komsindo webhande elishelelayo ngenxa yokugcoba noma ukwelula;
•       Ukuqhekeka kanye ne-brittleness;
•       Ukuphuka kohlaka noma imicu ngayinye;
•       Ukuxega nokuguga kwendawo eseceleni.

Ibhande le-compressor drive eline-hydraulic tensioner liyashintshwa ngale ndlela. Okokuqala, i-casing evikelayo ye-hydraulic device iyasuswa. Ukushuba kwesimo se-compressor drive kuthukululwa ngokufaka isikrufu se-hex kubhawodi ye-idler roller.

I-wrench kufanele iguqulwe kancane kancane ngokwewashi ukuze kuqinisekiswe ukuthi i-hydraulic tensioner iyanqamula ibhande futhi ibhande le-compressor drive lingasuswa.

Ukufaka ibhande, kuyadingeka ukususa ngokuphelele i-tensioner ngakwesokudla bese ufaka ibhande elisha, ngokusho kwesakhiwo sayo. Qinisekisa ukuthi unake iqiniso lokuthi ibhande lihambisana kahle ne-grooves noma ukungena kwama-pulleys.

Uma idivayisi yenziwe nge-tensioner mechanical, kuzodingeka ukuthi ukhiphe i-tension roller ngokuguqula isikrufu sesokhethi ku-hexagon yangaphakathi bese ususa ibhande lokushayela. Uma ufaka ibhande elisha, i-roller izosetha ngokuzenzakalelayo ukungezwani. Amandla we-tension we-roller awalungiseki. Kudingeka futhi uqinisekise ukuthi ukungezwani kwebhande kuma-pulleys kulungile.
